Five box model and chart


The LANDFIRE Program has created and delivered two critical product suites: spatial data sets and biophysical settings (BpS) models and descriptions.

SPATIAL DATA SETS

Spatial data map

 

LANDFIRE delivers more than 20 nationally consistent, 30m spatial resolution data sets for every acre in the US and larger island territories. These data sets represent current vegetation type and structure, current surface and canopy fuels, annual disturbance, and historic patterns of fire regime and vegetation. Data sets representing current conditions are updated every two years (LF2008, LF2010, LF2012, LF2014), and are publically available for download on the LANDFIRE program site along with full product descriptions. LANDFIRE is currently engaged in a Remap process to generate new base vegetations layers circa 2016.

Data Product Review Website - The purpose of this site is to provide a place where people can work through a review process of various LANDFIRE data products and a method for submitting feedback and suggestions on a number of LANDFIRE data products in a guidebook structure. The site is based on a content management platform with structured content for a dynamic web experience.  Feedback and suggestions will be reviewed both within and external to LANDFIRE and potentially improve future mapping updates and remaps.

BIOPHYSICAL SETTINGS

LANDFIRE produced and delivered state-and-transition models and descriptions for every major ecological system  (Biophysical Settings, or BpS) mapped by the program between 2005 and 2009 – information about vegetation dynamics, structure, and composition on lands across the U.S. prior to Euro-American settlement. 

Each BpS consists of two related parts: 1) a quantitative state-and-transition model, and 2) a description document published as a pdf file. The models were used in LANDFIRE to estimate reference conditions, which are used to help assess ecosystem health. The models were used in LANDFIRE to estimate reference conditions, which are used to help assess ecosystem health. In total, more than 700 experts were engaged to create 2,426 state-and-transition models (approximately 1,200 of which were unique) representing 783 mid-scale vegetation types in the U.S.

Biophysical Settings Review and Update: Almost Done!

Target date for product release is autumn 2018.

The 3-year LANDFIRE BpS review project engaged vegetation ecologists, fire managers and other land management practitioners in an effort to update and improve more than 1,000 BpS descriptions across the country. The review entailed reading and commenting on a 4-to-10 page MS-Word document at one’s own setting and pace (we estimate that a review takes less than an hour).

The engagement by experts across the country is impressive.
  • 8700+ BpS description documents were downloaded from the dedicated review site by local and regional experts, representing more than 95% of all BpS mapped by LF across the Continental US, Alaska and Hawai'i.

  • Additionally, more than 75% of all BpS have been downloaded five or more times, and some more than 50 different times.

LFDAT Compatible with ArcGIS 10.3 - 10.5             

The LF Data Access Tool (LFDAT) is an ArcGIS toolbar that allows users to interact with the LF data distribution site (DDS) and download LF data directly from ArcMap. Once the data are downloaded, it can automatically process the data into raster formats ready for analysis. LFDAT allows an ArcGIS user to drag a box in an ArcMap session to define a download area, select the desired LF layers, and then download data from the DDS for the specified extent rectangle. The downloaded zip files can be from any number of LF layers, can include single piece or multiple- piece downloads, and can include layers from any number of different spatial extent rectangles.

Once all the data of interest have been downloaded, the LFDAT Smart Assembler will batch unzip the files, merge multiple-piece layers back into a single output layer if necessary, and reattach attribute fields to the output raster attribute tables. Output raster layers can be generated in ESRI GRID, Erdas Imagine, or GeoTiff formats.

 

Fuel Data Product Released: Modeling Dynamic Fuels with an Index System (MoD-FIS)   

The LF team at the USGS EROS Center released new provisional products for the Great Basin and Southwest regions of the United States that capture the seasonal nature of fuels in this region. Modeling Dynamic Fuels with an Index System (MoD-FIS) incorporates seasonal variability of herbaceous cover (i.e. cheatgrass) to capture changes to fire behavior fuel models based on the current fire season herbaceous production.

Using current and historic Normalized Difference Vegetation Index data from the Landsat archive, LF developed a process to map current year herbaceous cover compared to historic averages. The result is updated Existing Vegetation Cover, Existing Vegetation Height, and Fire Behavior Fuel Model layers that reflect the current fire season herbaceous cover and resultant fuel availability.
 
These products are released multiple times per year, on a provisional basis, for all regions except the furthest north.
